Question No. 2

An Adobe Commerce developer has been tasked with applying a pricing adjustment to products on the website. The adjustments come from a database table. In this case, catalog price rules do not work. They created a plugin for getPrice on the price model, but the layered navigation is still displaying the old price.

How can this be resolved?

Show Answer Hide Answer
Correct Answer: C

The developer can resolve this issue by creating a plugin for the Magento\Catalog\Model\Indexer\Product\Price::executeRow() method. This method is responsible for updating the product price index.

The plugin can be used to add the pricing adjustment from the database to the product price index. Once the product price index is updated, the layered navigation will display the correct price.

Here is an example of a plugin for the executeRow() method:

PHP

class MyPlugin

{

public function executeRow(

\Magento\Catalog\Model\Indexer\Product\Price $subject,

\Magento\Catalog\Model\Product $product,

array $data

) {

$adjustment = $this->getAdjustment($product);

$product->setPrice($product->getPrice() + $adjustment);

}

private function getAdjustment(Product $product)

{

$adjustment = $product->getData('adjustment');

if (!is_numeric($adjustment)) {

return 0;

}

return $adjustment;

}

}

This plugin will add the adjustment data from the product to the product price index. Once the product price index is updated, the layered navigation will display the correct price.


Question No. 3

During database migration in the Adobe Commerce Cloud integration environment, a developer experienced a disk space error causing the database import to fail.

How would the developer fix this issue?

Show Answer Hide Answer
Correct Answer: A

The developer can fix this issue by increasing the disk space of the database service. The database service is one of the services that run on the Adobe Commerce Cloud platform and provide functionality for the application. The database service uses MySQL as the database engine and stores data for products, customers, orders, etc. The disk space of the database service determines how much data can be stored and processed by the database. If the disk space is insufficient, the database import can fail with a disk space error. The developer can increase the disk space of the database service by modifying the .magento/services.yaml file and redeploying the environment. Verified Reference: [Magento 2.4 DevDocs]


Question No. 4

When researching some issues with the indexer, an Adobe Commerce developer is seeing errors in the logs similar to Memory size allocated for the temporary table is more than 20% of innodb_buffer_pool_size. It is suggested that the client update innodb_buf f er_pool_size or decrease the batch size value.

Why does decreasing the batch size value improve performance?

Show Answer Hide Answer
Correct Answer: A

Decreasing the batch size value improves performance by reducing the memory usage for the temporary table. The batch size value determines how many rows of data are processed at a time by the indexer. A large batch size value can cause the allocated memory size for the temporary table to exceed 20% of innodb_buffer_pool_size, which can result in errors and slow down the indexing process. By lowering the batch size value, the indexer can process the data more efficiently and avoid memory issues. Verified Reference: [Magento 2.4 DevDocs] [Magento Stack Exchange]


Question No. 5

An Adobe Commerce developer is tasked with creating a custom block that will be displayed on every page in the footer of the site.

After completing and optimizing the development, the developer notices that the block takes too much time to be generated on each page and decides to store it in the system cache after enabling it for all cache groups.

What would be the minimum requirement to achieve this?

Show Answer Hide Answer
Correct Answer: C

To store a block in the system cache, the developer needs to set values for both the cache_lifetime and cache_key data properties of the block. The cache_lifetime property specifies how long the block should be cached, and the cache_key property specifies a unique identifier for the block.

The following code shows how to set the cache_lifetime and cache_key data properties of a block:

PHP

$block->setData('cache_lifetime', 600);

$block->setData('cache_key', 'my_custom_block');

Once the cache_lifetime and cache_key data properties have been set, the block will be stored in the system cache and will not be regenerated on each page load.
